Abstract: A freewheeling overrunning clutch for a bicycle, moped, and the like vehicle comprises a plurality of clutch pawls present between an outer wheel and an inner wheel which are supportable elastically on one side on the inner wheel circumference and on the other side on a plurality of inner teeth of the outer wheel. In order to provide a simple, almost noise free structure which is easy to mount, the clutch pawls pivotally supported in a flexible supporting ring positioned between the inner and outer wheels. Ends of the clutch pawls which face the inner wheel are brought into engagement with the plurality of teeth protruding outward from the inner wheel. The flexible supporting ring advantageously may simultaneously be a spacing ring for a plurality of balls of a ball bearing or bearings positioned adjacent the clutch pawls between the outer and inner wheels.

Abstract: A rapidly cleanable rotary atomizer is characterized by a passageway extending between a rearward coating material cup of the atomizer and a forward coating material feed surface, from an edge of which atomization occurs. The passageway initiates in the material cup at a non-zero radius from the atomizer axis and terminates on the material feed surface at the axis. During changes of coating material, the passageway enables flushing media to be introduced from the material cup onto the material feed surface immediately at the axis of rotation of the atomizer for quickly and thoroughly cleaning the entirety of the material feed surface.

Abstract: Material webs for producing folding packaging materials must be absolutely flat in order to make from them blanks (10) for folding boxes. Furthermore, punched indentations for folding lines of the blank (10) must be carried out in such a way that the foam material does not break along the folding lines when the blank (10) is folded. Known methods of the type discussed here have the disadvantage that the foam has to be heated up again in order that it can be rolled flat and embossed. The method according to the invention is intended to make this unnecessary. In order to make the subsequent heating of the material web (11) unnecessary, according to the invention the still "fresh" material web (11) is embossed. A flat material web (11) is produced by the permanent bonding of two contrarily curved web halves (18 and 19). The invention can be used wherever flat material webs (11) of foam plastic are to be produced or are to be provided with bending or folding lines (19).

Abstract: In particular for coating tools and product components, which are subject to extremely high wear, metal nitride films are used. It has been found that if the metals have markedly different melting points, in accordance with the invention, the concentrations of the metals can be varied as a function of the film thickness. For manufacturing such mixed nitride films by vaporization of metal alloy cathodes by means of an arc while simultaneously introducing nitrogen as reaction gas, a variable voltage is applied to the substrate during vaporization of the metal alloy and varied as a function of the film thickness on the substrate.

Abstract: The regulation system uses multiple integration of a feedback value to control the acceleration, the velocity and the displacement of the positioning drive. The feedback value is obtained from the difference between a reference acceleration value and the time integral of the amplitude limited reference value. An alternative reference acceleration value is supplied in dependence on the residual displacement path, to allow a constant retardation over a path ending at a point infront of the required end point. A second reference acceleration value is supplied, to allow displacement at a given velocity within overrun of the required end point. The second acceleration value is provided at 4 times the spacing of the first point from the end point.
